The track, 'Silver Lining (Crazy Bout You),' has yet to see an official release, but thanks to the magic of YouTube, you can hear it right now -- we've embedded the full-length clip above, complete with lyrics. It finds Ms. J crooning upbeat lyrics like "We got each other / That's all we need" over a stomping pop beat that wouldn't sound out of place on a OneRepublic hit. Jessie's team, however, went old school when it came time to find the song -- it was written by Diane Warren, the uber-hitmaker of the '80s and '90s who wrote chart-topping hits for bands like Chicago, Milli Vanilli, and Celine Dion.

The 'Price Tag' singer is currently dividing her time between her mentoring duties on the UK version of 'The Voice' and working on her next record, which is said to include an appearance by Cee Lo Green, and preparing for her upcoming tour. In the meantime, 'Silver Linings Playbook' is due to arrive in theaters on Nov. 21.
